With the development of the construction and decoration industry, interior decoration materials are developing toward three aspects of lightness, environmental protection and energy saving. Therefore, it is not easy to select lightweight partition materials in the interior. What are the materials for lightweight partition walls ? The following small series briefly introduces the material of the lightweight partition wall .
What are the lightweight partition materials?
1. GRC lightweight partition material
Glass fiber reinforced concrete; this is a kind of fiber cement composite material with alkali-resistant glass fiber as reinforcement material and cement mortar as matrix material. Aerated concrete block equipment foundation construction.
Its outstanding features are good tensile and flexural strength, as well as good toughness. This material is particularly suitable for making decorative shapes and for expressing strong textures. Compared with these exterior wall decoration materials, the greatest advantage of GRC materials is that they can meet the individual needs of the architects, and complete the expression of decorative shapes and textures.
2, fiber reinforced low-alkali cement construction slab.
The standard stipulates the classification, raw materials, technical requirements, test methods, inspection rules, packaging, marking, transportation and storage of fiber-reinforced low-alkalinity cement slabs. This standard is applicable to construction slabs made of chrysotile, chopped alkali glass fiber or alkali-resistant glass fiber, and low alkalinity sulphoaluminate cement.
Fiber-reinforced low-alkali cement slabs are mainly used for indoor non-load-bearing inner temples and ceiling slabs.
3, autoclaved aerated concrete slab
The autoclaved aerated concrete slab is a kind of lightweight, porous and new type of green building material with cement, lime and silica sand as the main raw materials, and then according to the requirements of the structure, a different amount of preservative-treated steel mesh sheets are added. Through high temperature and high pressure, steam curing, the reaction produces autoclaved aerated concrete slabs with porous crystals. The density of the autoclaved aerated concrete slabs is smaller than that of ordinary cement materials, and it has excellent fire resistance, fire resistance, sound insulation, thermal insulation, and thermal insulation.
4, light aggregate concrete planks,
It is mainly composed of foamed lightweight aggregate concrete slats with a layer of polystyrene foam interlayer in the foamed lightweight aggregate concrete slats. At least two sides of the four sides of the foamed lightweight aggregate concrete slats are arc-shaped. When the installation is completed, the connection between the two plates is rigidly connected in a double arc shape, and the connection is made of a material such as magnesium oxychloride cement as a cementing material. crack.
5, steel mesh cement sandwich panels.
The cores used in the front color steel sandwich panels are mainly phenolic foam, polyphenylene, extruded polystyrene, rigid polyurethane, tripolyester, and rock wool. The phenolic foam has excellent fireproof and thermal insulation properties. Instead, for example, the thermal insulation effect of phenolic foam is more than twice that of polyphenylene, and the fire performance is also higher than that of polyurethane. When the polyurethane is burned, it will release heavy smoke containing hydrogen cyanide.
6, gypsum wallboard
Using building gypsum as raw material, add water to stir and cast lightweight building gypsum products. In the production, it is allowed to add fibers, perlite, cement, river sand, fly ash, slag, etc., with sufficient mechanical strength.
7, metal surface sandwich panel
Metal-faced sandwich panels refer to upper and lower two-story metal sheets, and core materials are heat-insulating materials with certain rigidity, such as rock wool and rigid foam plastics. Also known as the "sandwich" board.
8, composite lightweight sandwich panel, strip
It is composed of two-sided medium-density cement fiber waterproofing board (100% asbestos-free) and light-weight aggregate concrete core (expanded perlite powder, polystyrene particles, light Portland cement, additives, etc.).
Features: Light weight, solid, thin body, high strength, sound insulation, heat insulation, waterproof, fireproof, moisture-proof, anti-freeze, anti-aging, strong hanging force, impact resistance, nails can be sawed, construction is simple, can be directly slotted Line tube.

Great develops and manufactures steel body and Matrix body coring bits using PDC cutters, thermally stable polycrystalline cutters (TSP), and combinations thereof. Diamond Coring bits is also named PDC core bits with PDC cutters and TSP cutters are designed for coring in soft, medium and hard formations, for maximum core recovery with high rate of penetration and its integrity preservation.
